Abstract: ABSTRACT    The present invention relates to a digital interactive communication system accessible to a plurality of subscribers who can select by means of their touch-tone telephones any of a plurality of pre-recorded video presentations representative of products and services for sale. In this system, the subscriber requests are received by a voice network interface which is coupled to a local area network.  A plurality of data processors, typically single-board computers, capable of various tasks are operatively connected to the local area network.  a number of these data processors are each dedicated to serving one subscriber during a requesting session.  Other data processors coupled to the local area network provide either navigational, subscriber, or purchase information during a subscriber session.  Also coupled to the local area network is a large-scale data base which stores digital information representing the video presentations which are requested by subscribers for viewing on their televisions sets.          Coupled to the large-scale data base is a means, such as a second local area network, for transmitting the digital information representing the video presentations to a CATV network for distribution to the subscriber's television set.

Granted: 1992-12-15
Abstract: ABSTRACT A method of scrubbing a boiler exhaust gas stream containing pollutants comprising one or more of the acidic oxides of sulfur, nitrogen and carbon and compounds of any of the halogens while producing useful or benign products, which comprises contacting the stream with a solution derived from dissolving in water the soluble components of ash containing as solids one or more of alkali and alka-line earth metal salts to produce a basic (pH greater than 7) solution.

Granted: 1993-07-27
Abstract: Abstract of the Disclosure A  paperboard  wrap-around  article  carrier  which  has  end  panels foldably  connected  to  the  top  panel  and  to  gusset panels.   The gusset panels allow the end panels to be folded and maintained in a substantially vertical position.  The end panels extend beyond the lowermost ends of the gusset panels so that the foldable connections between  the  gusset  panels  and  the  end  panels  is  minimal,  thus minimizing  the  cumulative memory  of  the  fibers  in the  foldable connections  to  prevent  the  forces  generated  by  the memory  from unfolding  the  end  panels  and  snapping  them  up  out  of  place.

Abstract: Abstract of the Disclosure This invention is directed to a method and apparatus for  forming a glass sheet with differential gas pressure over opposite surfaces thereof.  The glass sheet is formed by the action of differential gas pressure over a forming area located on a curved exterior surface of a rotatable glass former.  The forming area moves on an arcuate path about an axis of rotation of the glass former. The glass sheet forming operation is carried out in an incremental manner by rotational contact of the forming area of the glass former and the glass sheet being formed.  Full dimensional control can be achieved, whereby glass sheets may be produced which are substantially identical copies of one another.

Title: Method and apparatus for detecting innovations in a scene
Inventor: KADAR IVAN
IPC: G08B13/194
Filed: 1989-05-24
Granted: 1993-06-01
Abstract: ABSTRACT A method and apparatus for detecting innovations in a scene in an image of the type having a large array of pixels.  The method comprises the step of generating a multitude of parallel signals representing the amount of light incident on a group of adjacent pixels (masks) and these signals may be considered as forming a n by one vector, Z, where n equals the number of pixels in the masks.  L such groups of adjacent pixels or elementary masks are used to geometrically cover the entire image in parallel.  The method further comprises the step of replicating the generating step a multitude of times to generate a multitude of Z vectors by taking multiple frames of observations of the image (scene).  These Z vectors may be represented in the form Zk, where k equals 1,2,3,...,m, where m equals the number of replicates.  Each of the Zk vectors are related to a vector .beta.k of three parameters by a measurement equation in a linear model framework, i.e. Zk = D.beta.k + ek, where ek is an additive noise term.  In one embodiment, a solution of the linear model yields the best estimates of the parameters ?k = DTZk, where DT is a three by four matrix, ?k is a three by one vector, and Zk is a four by one vector of the measurements. ?k includes three components Uk, Ak and .beta.k.  The values of Uk, Ak, and Bk are monitored over time, and a signal is generated whenever any one of these variables rises above a respective preset level.

Abstract: ABSTRACT OF THE DISCLOSURE          After positional information of the master arm is transformed into first generalized coordinates corresponding to positional information representing an instruction position of the slave arm, when a signal instructing an interruption of the associated operation between the master arm and the slave arm is received and then the positional relationships between the master arm and the slave arm connected thereto by use of an imaging device are updated, the first generalized coordinates are transformed into the second generalized coordinates based on the new positional relationships so as to restart the associated operation therebetween. The optimal control of the manipulator is conducted through matrix operations related to the change-over between imaging devices, the reset operation conducted in an area of the movable range of the master arm, and the alteration of the ratio between the movements of the associated operation.

Abstract: A drainage device having a collection chamber for receiving liquids and gases from the body of a patient, an underwater seal chamber and a one-way outflow valve is disclosed. A partition extending across a portion of the device forms the underwater seal chamber, which prevents the flow of atmospheric air from the device into the pleural cavity of the patient, above the partition and the collection chamber below it. The underwater seal is created at the lower end of an extension connected to the inlet to the device by liquids drained from the patient. The one-way outflow valve communicates with a trap chamber for collecting liquids inadvertently conducted toward said valve. The trap chamber is closed off from the underwater seal chamber but is connected to the collection chamber by means of a passageway through a wall separating the trap and collection chambers.
